Just got done reviewing this map, thus far I give it a 7.5/10! One of the better ones out there currently! My constructive criticisms thus far:
1. Add fish and plants to some of the rivers/lakes that are lacking them. Lilly pads and cat-tails come to mind!
2. The dirt texture for the conifer woods is too lightly colored in my opinion, making it shades darker will make it look much more blended and nice as opposed to the lighter color which looks like desert soil imo.
3. The vanilla The Island jungle trees really don't mesh well with the custom assets you made/bought. I'd probably get rid of them since they are outdated and under-textured compared to your more recent assets which are more updated. As well the older The Island corals in the Inland sea don't go well with the much nicer looking Gen 1 corals.
4. Certain spots lack ambient noises but this isn't a big issue as the map is WIP. If you want some sound files for birds, insects, frogs, etc. I have plenty if you want to contact me!
5. Some of the spawns are messy(I would personally not use Genesis 2 spawners since they literally toss everything together) and would probably be better if you made custom spawners for all the regions. Any modded creatures can easily be slotted in via Simple Spawners.
6. Some ocean creatures spawn on land dead :P


So far so good, these are just things that stick out to me! :)
